RAID 1
A paging file on a RAID 1 array may benefit from a faster access time. But because the paging file has to be mirrored on a second hard disk, this greatly degrades the paging file's write performance. In addition, the paging file will not benefit from the additional data redundancy offered by RAID 1.
Therefore, it is recommended that you do not put your paging file in a RAID 1 array. You should place the paging file on a separate hard disk.
